I Was Stripped of My Waistcoat Because of My Poor Acting Skills and My Memory Was Deleted [Western Fantasy]

In this world, four key races are on the verge of extinction: the violent dragons often fight each other; the timid and cowardly Spirit Wings are forced to participate in a tragic coming-of-age ceremony; the Black Wings are coveted for their stunning appearance and are lazy by nature; The strict self-discipline of the White Feather Clan is the most normal, but they have one of the most fatal weaknesses: they are ruthless by nature, especially the men. They don't even respond to the stunning Black Wing Clan, and they can only rely on women who still have a little tenderness to reproduce the race. The IEVK of the Time and Space Administration uses vests of various races to fix the bugs of each race conscientiously, but she can't open a small account to get in with the White Feather tribe. After all, they rarely have children! In order to attract the studious White Feathers, she united with various vests to open a school in the center of the mainland that provides education without any distinction. Then because her acting skills were so poor, she couldn't keep her vest. She was just a technician, not a movie queen! She immediately abandoned the vest that had completed its mission, only to be blocked by the Wing Clan who had lost their beloved. Just when IEVK was distressed, all the passages in this experimental world were suddenly blocked. Without the help of the Space-Time Administration, she spent thousands of years waiting for the strongest body with the blood of the four races to open the space-time passage. Because her previous acting skills were so poor, she decided to delete all her memories when she used this vest. But just when she met the conditions and read into her memory, she saw a beautiful girl smiling at her like a winner. She said, "Thank you, this body is mine now." Purpose: Work efficiently and avoid overtime
